To all 't0/lam it may concern.'

YBe it known that I, MICHAEL l\V/.[YsI.IwIoz,`v a subject of `Emperor ofAustria-Hungary,

` residing at Vehrmn, in the county of Indiana and Statey ofPennsylvania, havefin-u vented certain new and useful Improvementspin`Coal-Cutting Machines, ofwhichy the following is a specification,reference being had therein tothe accompanying drawing. i

This invention relates to a coal mining machine, and the prima-ry objectof my in-` vention is to provide Va hand operated machine whereinsimpley and effective means are employed, as hereinafter set forth forimparting an oscillatory movement to a plurality of mining bits, wherebya horizontal kerf can be economically and expeditiously produced butpermits of .coal being broken down and easily mined.

A further object of this invention is to provide a machine of the abovetype that can be easily, quickly `and advantageously used for performingsuch work as ordinarily accomplished by the use .of a pick,'namely,

that of providing a kerf or slot whereby a,

body can descend by gravity or be shattered by resorting to the use ofan explosive.

A still further object of this invention is to provide a hand opera-tedcutting machine Figure 1 is a plan of the machinel in a horizontal'position,`with parts broken away'.v Fig. 2 is a side elevation of themachine with the breast piece removed, and parts broken away. Fig. 3 isan enlarged cross sectional view of a portion of the machine. Fig. 4 isa horizontal sectional view .taken on the line IV-IV of Fig. 3. Fig. 5is a similar view taken on the line V-V of Fig. 3. Fig. 6 is an enlargedperspective view of a por` tion of a lever with a scraper adapted toform part of the machine. Fig. 7 is a detail view in cross sectionillustrating the swveled breast bar.

A cuttingjmachine in accordance with this invention comprises twoparallel semi-circular frames 1 having the ends'connected by an Integralcross-bar 2 and this bar, Interconnection' between the rhousing and thekmediate the ends thereof yis provided with a slotB, the purpose ofwhichwill presently appear. The bar 2, at the ends thereof, is

` sl0tted,"'asat y1 and pivotally `mounted in said slots by transversepins 5 are the ends offhand operating links 6. These links are flat andthe outer `ends of said links are prow vided with hand grips 7 The upperside of each link is provided With transverse equally spaced v pivot'edscrapers 8' that` are hinged, as at`9 to the links. The scrapers 8 areadapted to lie flat y againstthe link as the link moves into` a kerf,but as the link is pulled out of the kerf,

the scrapers 8 assume a` position at right angles to said links, wherebythey can remove coal or'other matter from va kerf produced by the"machine To maintain the scrapers 8 at right angles to the link 6, saidlink is provided with depending parallel pins 10, and these pins bracethe scrapers while the same areimpingingfandremoving y coal from a 1jkerf.' n

Arranged upon "the" outer sides of the frames 1 are a plurality ofequally spaced cutting bits 11, said bits having reduced ends 12'mounted in sockets 13 provided therefor in the frames 1`. Thisconstruction is best shown in Fig. 3. The inner side of one oftheframesl isfprovidedwith aplurality of equally spacedinwardlyprojecting pins14, and these pins are adapted to engage i a pin`wheel 15 that is mounted upon the" The shank 160i shank 16 of an au ger17a.-

the auger 17 ais rotatably mounted in a ycylindrical head I17i`andthisjhead is provided with circumferentially arranged ratchet f teeth 18adapted to be engaged by a refV 'silient pawl 19 carried by the lowerside lof the pin'wheel 15. The shank 16 is provided with a flange 16awhich constitutes a support for the head 17 The 'head 17 is lixedlysecured to the shank 16 whereby the head 17 and shank 16 willturn'together.l

ioo`r The cylindrical head v`17 has oppositely y disposed arms 2Oand'saidy arms are iXedly connected, as at 21 `to a `rectangular housing22, carriedby the outer end ofa breast bar 23. The housing 22 isswivelly connected 'to the breast bar 23and as said`housing'22 is iXedtothe head 17, the saidhousing head swivel together upon the breast bar,

and as the shank 16 is connected to the headv a 17, it is obvious thatsaid shank, head and housing turn together. The breast bar 23 extendsthrough the slot 3 of the bar 2 and is pivotally mounted Within saidslot by a transverse screvv or pivot 24:. The breast` bar 23 has anadjustable telescopic sleeve 23a provided with a pivoted breast piece23h.

To place the cutting machine in operation, it is only necessary torotate the auger 17a sul'iiciently for the same to engage in a body ofcoal and support the frame 1 relatively.` to the body of coal. Theplacing of theV auger 17a in engagement with the body of coal can beaccomplished through the medium of the breast bar 23. By then grippingthe links 6, `the frames 1 can be oscillated relatively to the breastbar 23.' A

movement of the frames 1 in one direction` Y sequently coal is removedfrom the kerf and the operation of the machine not interfered with untila kerf, Within the scope of the machine has been cut.

By arranging one-half of the cutting bits 11, in an opposite directionfrom the other half,y alquadrant of the kerf is cut at each oscillationof the frames 1, and each alternate operation of said frames feeds themachine `farther into a kerf or body of coal,

thus permitting of a body of coal being un-I dermined in a small space'Where a pick or other implement could not be easily 'manipulated.

The machine inits entirety is constructed" of 'soft and 'durablemetahand While in the drawing', there is illustrated a preferred embodimentof 'the invention, it is to be understood that the structural elementsare susceptible to such variations and modifications as fall .Within thescope of the appended claims.

Vhat I claim is 1. A cutting machine including parallel semiv circularframes, a bar connected to said frames, a handle bar pivotally connectedto saidv bar, anl auger loosely supported by said handlebar and adaptedto have movement imparted thereto by an oscillatory movement of saidframes, and links connected to the bar of said frames to facilitate anoscillatory movement to said frames.

2. A cutting machine comprising parallel imparted thereto by anoscillatory movement of said frames, links connected to the .barof saidframes to facilitate an oscillatory movement to said fra-nies, aplurality of bits carried by said frames, and hinged Scrapers carried bysaid links. 3. cutting machine including semi cireular frames, a barconnecting said frames, cutting bits ycarried by said frames, links.pivotally connected to said bar to facilitate imparting anoscillatorymovement to said frames, Scrapers carried by said links, means includingan auger for anchoring said frames relatively to a body of coal, and abreast bar carrying said means and having the said bar pivotallyconnected thereto. i Ll. `A kerf-cutting machine comprising parallelsemi circular frames, a bar con-v necting said frames, links connectedto said bar for oscillating said frames, bits carried by said frames, abreast bar supported by the bar of said frames, an auger movably4supported relatively to said breast bar and adapted to anchor saidframes relatively to a `body of coal, and means actuated by anesci'llatory movement of said frames for feeding said auger into a bodyof coal whereby a kerf can be produced by oscillating said frames.
